PAKDA a Russian Stealth bomber

The PAK DA (or PAK-DA), is a next generation strategic bomber which is being developed by Russia. It stands for Perspektivnyi Aviatsionnyi Kompleks Dalney Aviatsyi which means Future Air Complex for Strategic Air Forces. The PAK DA is going to be heavily based on Russia’s current supersonic bomber Tupolev Tu-160 and is expected to have it’s maiden flight by 2015.

Russian Air Force has made tactical and technical requirements for a new generation of strategic bombers, as reported Interfax.

According to Russian Air Force commander Aleksandr Zelin, work on a new bomber has already begun. “The requirements are formulated, and many firms are now implementing plans” – said Zelin.

According to available information, the aircraft being developed under the project PAK DA (prospective aviation complex long-distance aircraft), will be computed on the basis of construction of a supersonic Tu-160 bomber. According to specialists, to create a new aircraft will take from 5 to 8 years, and the first flight of bombers to be expected after 2015.

Currently, the Russian airforce has Tu-95 and Tu-160 strategic bombers, as well as long range Tu-22 bombers. They can carry bombs and cruise missiles. The aircraft of these types are currently undergoing modernization.

Reports also say that the new bomber will have stealth characteristics.

MOSCOW, November 14 (RIA Novosti) - Russia's future PAK-DA manned bomber project will not have hypersonic speed capability, Russia's bomber force commander said on Wednesday, in an apparent contradiction of claims by Deputy Prime Minister Dmitry Rogozin earlier this year."PAK-DA, currently under development, will not be hypersonic," Lt. Gen. Anatoly Zhikharev told RIA Novosti on Wednesday.The first prototpe PAK-DA is due to enter service around 2020, he added.Hypersonic speeds are high supersonic, usually referring to Mach five and above, which can usually only be generated using advanced propulsion technology such as ramjet or scramjet engines. No manned aircraft has yet been flown using such technologies, which are on the cutting edge of aerospace know-how.Zhikharev's statement follows a protracted exchange in the media between senior air force officers, including himself, and Rogozin, who has special responsibility for the arms industry, over what shape PAK-DA should take.Rogozin repeated in August an earlier appeal for Russia to develop a hypersonic aircraft for its PAK-DA long-range bomber requirement."I think we need to go down the route of hypersonic technology and we are moving in that direction and are not falling behind the Americans," he said on Rossiya 24 TV. "We will use this technology when developing a new bomber."In June, President Vladimir Putin ordered initial development of the new long-range bomber for strategic aviation. Speaking during a conference on defense orders, Putin said: "We have to develop work on the new PAK-DA long-range bomber aircraft for Long-Range Aviation. The task is not easy from a scientific-technical standpoint, but we need to start work."Rogozin initially said in June he saw no need for PAK-DA to replace the air force's aging Tu-95MS cruise-missile carriers and Tu-160 supersonic bombers.“These aircraft will not get anywhere. Not ours, not theirs,” he said in an interview with Izvestia that month. He later clarified his statement by saying he was in favor of developing a future bomber, but it should not just be a copy of the serving US Northrop B-2 and should employ hypersonic technology.In May, he called on Russia's defense industry to develop hypersonic air-breathing weapons as a future strike system. He cited American development work in the X-51, Falcon, HiFire and HyFly hypersonic programs as examples of what he described as the perspective threat posed by U.S. hypersonic development work.Some aerospace analysts RIA Novosti has previously spoken to say Rogozin's comments are more likely to be relevant to a future air-launched missile, rather than the bomber that launches it.

Development of complex long-term aviation aircraft (PAK DA), which will replace the strategic bombers Tu-95MS and Tu-160, will begin in 2014. On this, as reported by "Interfax" , said the Chief of the General Staff of the Russian Armed Forces, Army General Valery Gerasimov. Other details about the project general did not disclose.

The project is prospective bomber was approved in early March 2013. It was reported that the variants of the new aircraft offer several design offices, but the Main Command of the Russian Air Force chose the project Tupolev Design Bureau, who proposed a military subsonic aircraft with extensive use of stealth technology.

It is expected that the forward-looking strategic bomber will be built on a "flying wing". "Tupolev" will finish the work on the tactical and technical characteristics of the PAK DA until the end of 2013 and in early 2014 the Ministry of Defense of Russia will present a calculation of the budget of research works on the project. According to current plans, the mass production of bombers to begin in 2020.

The profile of the PAK DA was completed in mid-2012. Previously, it was also reported that the prospective bomber will not be a deep modernization of the Tu-160, and Russian Deputy Prime Minister Dmitry Rogozin called on not to create a "copy B-2", U.S. strategic aircraft.

United Engine Corporation (UEC) of SC Rostec successfully conducted its first prototype engine bench tests for prospective long-range aviation complex (PAK DA). This sample is planned testing of the parameters corresponding to a given flight characteristics of the object, the press service of the DCS

As part of the program to create the engine for the PAK DA specialists of JSC "Kuznetsov" reconstruction of the test stand for experimental techniques: Submitted complex construction and engineering, provide the connection to the stand of the new measurement system, updated control room equipment for testers. Thereafter, the prototype motor has been assembled and mounted on the stand.

In the course of the tests showed the product characteristics, close to what is required. Currently, development work on this subject continues.

"The first successful launch of the pilot product for enterprise staff is a significant point, because there is the successful implementation of the R & D achievements in the actual production," - said the executive director of "Kuznetsov" Nicholas Jakushin.

It is planned that the first flight of the PAK DA will be held in 2019
